To n.1/ 'wh/nu, it may concern:

' Be it known that I, ZION E. FrvEAsH, a citizen of the United States,residing at Rawles Springs, in the county of Perry and State ofMississippi, have invented a new and useful Still, of which thefollowing is a specification.

This invention relates to improvements in apparatus for distilling woodin order to obtain the various products--such as creosote, turpenti'ne,and the like-therefrom.

One of the principal objects is to provide novel means of a simplenature that will effct a thorough heating of the material and a completepermeation of the Same with steam, said steam being, furthermore,employed as a vehicle to carry the desired products from the retort to acondenser.

Another object is-to provide simple and efiicient means for removing therefuse from the retort with rapidity in order to permit the A use of theapparatus with successive charges and without any great waste of timebetween the charges.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein l Figure l is a view in elevation of thenovel still. Fig. 2 is a longitudinal sectional View through the retorton the line 2 2 of Fig. 1. Fig. 3 is a horizontal sectional view throughthe same. Fig. 4 is a detail sectional view on the line 4 4 of Fig. 2.Fig. 5 is a vertical sectional view through the condenser. Fig. 6 is adetail View of a portion of the chain,.illus trating the detachablelinks. Fig. 7 is a detail view of one of the still-doors and theassociated portion of the guide-trough.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated the retort consists of a tubular orcylindrical upright body 6, having a top end wall 7 and a bottom endwall 8. Within the body and contiguous to its lower end is arranged apartition 9, that subdivides the interior of the body into an upperretort-chamber 10 and a lower steamchost 11. Stay-bolts 12 connect thebottom 8 and partition 9, and a suitable steam-supply pipe 13communicates with thel chest and' has a controlling-valve 14.

A plurality of tubular connections in the form of pipes 15 extend lonitudinally through the retort-chamber, their ower ends being suitablysecured to the partition 9 and communicating with the steam-chest, theirupper ends being fastened to the top 7 and projecting therethrough, caps16 being screwed uponthe projecting ends to close the same. These pipesare preferably formed of sections coupled together, as shown at 17, andthe portions located within the 4.retortchamber are perforated, asillustrated at 18. These steam-pipes constitute stays between thepartition 9 and the stop 7. i

A charging-opening 19 is formed in the top 7 and is normally closed by acover 20, thatl is fitted against the inner side of the top 7 and has astem 21 passing througha holding-yoke 22, that bridges the opening 19. Anut 23 is threadedonto the. stem 21 and bears against the yoke, thusholding the cover 2() in place.

yThe joint between the cover and top is suitably packed, as shown at 24.In the lower portion of the retort-chamber are formedoppositely-'disposed doorways 25, arranged to be'closed by hinged doors26, having packingaskets 27 and locked by swinging bolts 28, lustratedparticularly in Fig. 4. Operating through the lower portion of theretort-chamber 10 and through the doorways'is an endless conveyercomprising a chain 29, of detachable links, passing about pulleys 30 andcarrying transversely-disposed scraper-blad es 3 1. Guide-troughs 32 arelocated on opposite sides ofthe retort in line with the doorways, andthrough these troughs the said conveyor runs. The inner ends of thetroughs 32 consist of swinging sections 33, which may be dropped down inordcr to permit of the Opeli-l ing and closing of the doors, beingsupported by suitable removable blocks 34. Any other structure that isfound desirable may be sub- The constituted for the swinging sections.veyer when traveling. through the retortchamber is guided by strips ofangle-iron 34a, which embrace the chain, yas illustrated in Fig. 2.

Leading from the upper portion of the retort-chamber 10 is anoutlet-pipe 35, the inlet end of which is covered by a screen 36, saidoutlet-pipe having a controlling-valve 37 therein. Thisoutlet-pipe isprouided'with a dip 38, to which is connected a depending creosoteoutletipe 39. The outer end of the pipe 35 is ownturned and coupled, asshown at 40, to the upper end of the worm 4l IOO of a condenser,said'worm being located in a @to y the condenser.

suitable tank l2 and having` its lovrer end projecting therefrom, asshown at d3, said projecting end having a dip therein. A gasvent is islocated betiveen this dip and the tank. v

Any suitable means may be employed for supplying' material to theretort. Said material is preferably iinely divided and is in the form ofsmall pieces-chips, sawdust, and the like. in the present instance thismeans consists of an endless conveyer (a portion of which is shown at45) that leads from the mili in which the material is prepared. A chute46, associated with the conveyer, has its discharge end disposed abovethe top of the retort and in a position to deliver the in aterial.through the'charging-opening 19. A steamgage i7 may be connected by apipe 48 with the retort-chamber.

Before charging the retort the section oi the conveyor that is Withinsaid retort-chainber is uncoupled from the remainder of said conveyor,and this may be readily accomplished, for, as already stated, the chainconsists of detachably-associated links. The

doors 26 are then closed and fastened, While the cover is removed fromthe charging-opening.

Material is then supplied to the retortchamber by the conveyor45,-lwhich isdriven in any suitable manner, and when the cham- .g

oerl 1s partially or completely filled the cover -20 is replaced andfastened. Steam is thereupon turnedl into the steam-chest through theIsupply-pipe 1 3 and, passing through the periorated pipes 15, willthoroughly perme- -ate the material in the chamber, opening the poresthereof and carrying the volatile products through the screen 36 andoutlet-pipe 35 The heavier products, lsuch as creosotc, will iind theirWay through the pipe 39, While the turpentine and other distillates,being condensed in the Worm 4l, Will escape through the projecting pipe43. Atti-inthe charge has been thoroughl Y treated vthe steam is shutoli, the doors are opened, and the section ot the conveyer Within theretort-chamber again coupled to the remaining portions of said conveyer,Whichris then operated by any suitable means. It v'ivill thus be seenthat the refuse is quickly carried from the chamber and may be deliveredto any suitable point desired.

heating oi" the material, and the steam, which racts as the heatingmedium,v will completely 4permeate the charge and will, furthermore, act

sita-sae struction may be resorted to Without departing` from the spiritor sacrificing any of the advantages oi" the invention. f

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-
